Genus Trigonexora Bechyné & Bechyné, 1969

Trigonexora Bechyné & Bechyné, 1969: 90 (type species Exora stilodina Bechyné & Bechyné, 1962 , by original designation).

Remarks

This genus currently contains only four described species, but some of the species currently in Exora probably belong here. Numerous apparently undescribed species also belong in Trigonexora . The males of some species have a curious, slender appendage on the abdomen, but the males of other species do not. The genus occurs in South America. See Figs 62 and 200 .
